Well I’ve been in Japan for about 2-3 weeks and I have to say… a lot of advice here doesn’t work. I mean, a lot of advice is good, don’t get me wrong, but a lot of it isn’t quite right either. For example, I talked to Kim1234 (qualified for SBO this year defeating several grandmasters in the process) and he lists Abel (in normal SF4) as 6.5/3.5 and says it’s Bison’s hardest matchup. Of course, I don’t think America has a lot of great Abels so this can be hard to believe, but everyone here has such an insane knowledge of the game it’s crazy.
As for certain matchups being “easy”- Japanese Zangiefs will make you cry if you think they’re easy. They don’t walk or jump into random st. roundhouses and they’ll greenhand the crap out of your roundhouse (and FADC out of it so that you can’t punish).
Once Rufus gets in, you’re eating throw unless you would rather eat a big combo. And any competent Rufus WILL get in. Standing roundhouse is good against Rufus, but it’s not the be-all-end-all move. Any good Rufus can get around it. His mobility with dive kicks makes the standing roundhouse seem slow.
Kim1234 says the Abel match-up goes like this: Abel whiffs Tornado Throw for meter and Bison can’t punish this. As soon as Abel makes Bison block cr. mk (I think that’s the move he was talking about), it’s a guessing game for Bison that’s definitely in Abel’s favor.
Anyway, that’s all I got for now.
